Specification of Letters Patent.

Application filed January 24, 1908. Serial No. 412,467.

To all whom it may concern.

Be it known that I, Josnrrr A. McCon- NELL, aflcitizen of the United States, residing at Dallas, in the county of Polk and State of Oregon, have invented a new and useful Chock Attachment for Cars, of which the following is a specification.

This invention relates to logging cars and the like and more particularly to chock attachments designed to be secured upon a car for the purposeof holding logs or timbers against displacement upon the car.

Another object is to provide an adjustable chock which, when in operative position, is securely held in place and can not be forced accidentally out of proper position.

Another object is to provide novel means whereby chocks can be moved into lowered position, said means being so disposed that there is no danger of the released lo s falling upon the operator.

Another object is to provide simple means for detachably securing the attachment to a car.

With theseand other objects in view the invention consists of .certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 a plan view of a, portion of a car having the attachment thereon. Fig. 2 is a longitudinal section throug'l'i the attachment, said section being taken transversely of the car platlorm and the chock being shown in elevation. F 1g. 3

is a detail view of one of the combinedguides and stops used in connection with each chock. Fig. 4 is an outside elevation of one of the chocks. Fig. 5 is a section on line :r-m, Fig. l.

Referring to the figures by characters of reference, "A designates a car platform of any preferred construction and the side sills thereof are designed to be engaged by the hooked ends 1 of bolts 2 which'extend downward through and are secured within the ends of parallel beams 3. These beams extend transversely of the platform and are arranged in pairs. Parallel actuating shafts 4- and 5 are journaled within the n'iiddle portions or all of the beams employed and extending from the middle portion of each t of these shafts is an arm 6 to which is pivotally connected the forke end 7 of an actuating rod 8. These rod extend toward opposite sides of the platform and are provided with grips 9 at their outer ends so that they may be conveniently manipulated. Openings 10 are formed within each rod and designed to receive the ofl'set end 11 of a holding member 12 which is bolted or otherwise fastened to the car platform. A retaining pin 13 may be extended down-. ward through the offset end of each holding member and into the car platform as indicated in Fig. 5, said pin serving to confine the operating bar 8 and fprevent it from accidentally slipping ofi" o the end 11 engagmg 1t. Secured to the adjoining faces of the beams 3 of each bar are combined guiding and stop devices such as shown in Fig. 3 and each of which consists of a face plate 14 having an integral longitudinall extending ratchet bar 15. A longitudmall channeled guide ltl-is formed integral with plate 14 and located above but beyond the side of the ratchet bar. Four of these guide and stop devices are used in connection with each pair of beams 3, said devices being arranged in pairs as indicated in Fig. 1 and adjacent the ends of the beams. Interposed between the stop devices of each pair is a chock consisting of a bowed or curved arm 17 having trunnions 18 designed to travel within the guides 16. Those portions of the guides and above trunnions outside of the the ratchet bars 15 are provided with cam faces .19 terminating in shoulders 20 designed, when the arm 17 is swung upward, to turn downward into engagement with the adjoining teeth of the ratchet bars. An arm 21 extends downward from each of the chooks and pivotally connected to it is a link 22 having a series of apertures 23 any one of which is designed to receive a wrist pin 24 extending from arm 21. Thelink 22 of one of the chocks is connected to a crank arm 5 extending from the adjoining shaft while the chock at the other side of the car is similarly connected to the crank arm'25 extending irom the ,other shaft 4.

.iis heretofore stated any desired number of checks may be secured upon the platform and the pairs of beams 3 can be adjusted toward or from each other so as to hold either long or short logs. This adjustment permissible in View of the facts that the shafts 4 and 5 extend through all of the wor dly,

be partly rotated and motion will be translower side of the car "finitted through arms 25 to links 22.

'21 will therefore be swung outwardly and beams, hired means for enga Arms move the shoulders 20 downward into en- .gagement with the adjoining ratchet teeth. This operation Wlll bring the shaft 5, wrist 15 pin 24:, and the pivotal connection between link 22 and arm 25 practically in alinement so that each chock becomes locked in an elevated position and it is impossible to lower it by exerting pressure thereagaihst. Logs can therefore be loaded upon the fear and will be held securely infplacevby the-elevated chocks, said logs restingupon the beams 3 and located above the shafts t and 5 and their connections, -When it is desired to dump the logs the car .is placed inauinclined position and the-'pperator goes to. the elevated side of the car and pulls out- This causes the shaft to which the bar is conrotate and to p'ull on its wardly upon the operating arm 8,

nected to partly link 22. The" arms 21 of the chocks at the wardly simultaneously tion of the trunnions' w serves to withdraw the shoulders 20 from en gagement with the ratchet teeth and the: chock is free to swing inwardly. The logs will therefore roll o'ii. of the lower side of the car and all danger of injury to the operator who is positioned the other side thereof is eliminated. What is claimed is: 1.151) attachment for cars comprising parallel. beams, means for securing the beams to a car platf um, oppositely disposed checks oivotall 1 and movably. mounted between the ing the checks when elevated only to ll0l( them against sliding movement in one direction, and means carried by the beams for actuating the An attachment ior cars con'iprising beams, combined stop and. guide devices fixedly carried thereby, cho'cks pivotally and will thus be pulled inandthe partial rota ich is thus produced-j downward and move limit the movement of the chocks in one di- 1 motion, and separate means for elevating l l l the checks.

4. An attachment for cars comprising beams,- combined guide and stop devices fixedly carried thereby, chocks pivotally and slidahly mounted within said devices, means integral with the chocks for engaging the devices only when the chock is raised to limit the sliding movement of the chocks in one direction, and means extending toward one enkl of the beams for actuating the chock adjacent the other end thereof.

-5. in attachment for cars comprising beams, a chock pivotally and slidably mounted between the end portions thereof, a shaft jou naled within the beams, a crank arm carried fthereby, a link connection between said armland check and means cooperating with thefchock for limiting its movement in one direction, said crank arm and link being disposed to lock the chock in an elevated positron.
